abstract = {The energy sector is a complex ecosystem in which many actors participate. In the EU, the energy sector is changing significantly as part of the energy transition. One important change is decentralization of energy, for example the bilateral trade of energy between households generating energy by solar panels and consuming energy. A key question is how to design the decentralized governance structure of such an ecosystem. We propose the DECENT (decentralized) ontology, which results from an extensive literature study in the field of decentralized governance in the energy sector, which allows to describe governance in ecosystems in a structured way. Its intended user-base are business developers and ecosystem designers. The DECENT ontology provides the terminology to represent and analyze important governance constructs for these stakeholders. We demonstrate the practical use of the ontology by means of a case study about peer-to-peer energy trading.},

abstract = {Blockchain systems are a new way to reduce or even eliminate the role of the middlemen in an eco-system. For example, the Bitcoin, as one of the most well-known blockchain platforms, shows that it is possible to transfer money without the need of any (intermediate) bank at all. More generally, it allows for the decentralization of roles. In this paper, we focus on permissionless blockchains, which are systems that allow participation without upfront approval on other parties, as opposed to permissioned blockchains. Permissionless blockchain systems support direct business transactions between peers, so without any intermediate and centralized entity very well. However, the organization of the governance of such systems is less obvious. We argue that, in order to arrive at a really decentralized eco-system where power is fairly distributed, the governance should be decentralized; in other words, it should not be in the hand of one controlling entity. In this paper, we analyse, in a model-based way, for three well-known blockchain systems (Bitcoin, Ethereum, Tezos) the governance processes. Based on this analysis, we draft an improved governance process for permissionless blockchains.},
